1.0 INTRODUCTION MODEL GWL08US This Service Supplement contains information on the Product Specifications, Diagnostic Mode and the Detailed Fault Codes. For all other Service and Option Adjustment information please refer to your GWL03 Service Manual part number 426348. Note: The water temperature adjustment in the Option Adjustment mode is only available on model GWL03. -
Page 4: Machine Size Setting Mode
2.0 MACHINE SIZE SETTING MODE It is important to set the size setting into the Motor Controller's memory whenever a replacement Motor Controller or Display Module is fitted to the washing machine. Failure to do this will result in the machine faulting to detailed fault code 9. The size setting procedure for GWL08 differs from the previous GWL03 Smart Drive... -
Page 5: Diagnostic Mode
3.0 DIAGNOSTIC MODE The DIAGNOSTIC MODE for mode GWL08 now incorporates both the switch test mode and the data display mode. You no longer have to use the advance button to toggle between them. To enter the DIAGNOSTIC MODE: 1. Turn the power on at the power point and off at the console. 2. -
Page 6: Lid Switch & Out Of Balance Switch Test
DIAGNOSTIC MODE cont: The following tests can be carried out in the diagnostic mode. 3.2 LID SWITCH & OUT OF BALANCE SWITCH TEST Press the SPIN SPEED UP button until the MEDIUM SPIN LED is on, (binary count 4). When the Lid is open the 12 minute wash LED will be on. Activating the Out of Balance lever under the top deck will cause the 6 minute LED to turn on. -
Page 7: Re-Start Feature
3.5 RE-START FEATURE WATER LEVEL DOWN button turns the RE-START feature on/off. LOW WATER LEVEL LED ON = RE-START ON. (Factory setting). LOW WATER LEVEL LED OFF = RE-START OFF. 1. If a fault occurs in the machine, the diagnostic system will detect it. However, instead of displaying a fault code immediately, the machine will try to RE-START. -
Page 8: Fault Display
DIAGNOSTIC MODE cont.: 3.8 FAULT DISPLAY If the machine enters a fault mode during normal operation, the machine will display the detailed fault code on the wash progress LED’s and beep continuously. The hold and slow spin LED’s will also be displayed. During the above process the beeper will sound continuously. -
Page 9: Detailed Fault Codes
5.0 DETAILED FAULT CODES INTRODUCTION The format for fault description in this booklet follows the Primary, Secondary and Teritary fault source system. These sources have mostly been arranged in order of most likely source of fault but in some cases the sequence has been modified to aid the servicing procedure. It should be noted that the fault source Pump System includes the pump and drain hose assembly. -
Page 10: Fault Descriptions
FAULT DESCRIPTIONS (00000001) Motor Controller Module Fault The Motor Controller Module has found a memory error. Primary Source - Motor Controller Module. Action - Replace Motor Controller Module. (00000010) Motor Controller Module Fault An error has been encountered when trying to read the pressure sensor. Primary Source - Motor Controller Module. - Page 11 Secondary Source - Motor Controller Module. Action GWL03 If the Motor Controller Module has been changed from one size machine to another, then the size switch settings in the memory will have to be reset. This can be done by entering and exiting the Option Adjustment mode.
- Page 12 (00100100) Water Leak Fault The Motor Controller Module has needed to top up the water level more than 4 times during agitate. This is excessive as normally only one or two top ups are required to replace the air that has escaped from a full load during agitate.
- Page 13 Tertiary Source - Motor Controller Module. Action Activate Pump by operating the machine in spin mode. Check Pump is rotating by viewing through the inspection hatch. If not operating and Primary and Secondary checks have been performed then replace Motor Controller Module. (00100110) Pressure Sensor Fault The Motor Controller Module has recorded a water level of empty while it is agitating.
- Page 14 (00101001) Temperature Sensor Fault The temperature sensor is measuring temperatures above 230°F (110°C.) The fault is probably due to a short circuit in the sensor line. Primary Source - Motor Controller Module. Action - Replace the Motor Controller Module. (00101011) OOB Switch Fault The Motor Controller Module has found that the signal returning from the out of balance switch indicates that the switch is permanently on or the harness to it is disconnected.
- Page 15 (00101101) Display Memory Check Fault On power up, the display has checked its memory against a known reference and found differences. Primary Source- Display Module. Action - Replace Display Module. (00101111) Basket Dis-engage Fault While carrying out a basket check, the Motor Controller Module has found that the basket is not engaged even though the pressure sensor indicates that the basket is empty.
- Page 16 (00110010) Hot Valve Faulty The Motor Controller Module has measured a voltage from the valve diagnostic circuit that indicates that the hot valve is faulty. The most likely cause is that the valve harness has not been connected correctly or the valves are open circuit. See fault 48 for service procedure. (00110011) Rotor Position Sensor Step Fail The Motor Controller Module has attempted a motor step test and has found that the motor has not stepped in the correct direction.
- Page 17 Check that there are no clothes or other foreign objects preventing the clutch from re- engaging, and that there aren’t any defects with the clutch mechanism. Next check that the pressure tube has not come off and that it is not kinked. Tertiary Source: Rotor Position Sensor.
- Page 18 106. (01101010) Display to Motor Controller Module Communications Errors These faults are reported when the Display Module detects an error in the communications between the Display Module and the Motor Controller Module. Primary Source - Display Module. Action - Replace Display Module. Secondary Source - Motor Controller Module.
- Page 19 1) Measure/check the motor harness, connectors and motor for shorts. This can be done by taking a resistance measurement between phases of the motor harness at the Motor Controller module end. Nominal resistance should be around 12.2 ohm. 2) Check the Rotor Positional Sensor and associated harness for water, mechanical damage or corrosion Tertiary Source - Motor Controller Module.
- Page 20 Secondary Source - Motor Controller Module. Action If the machine is empty of water at fault it is possible that the pump circuit is faulty and has caused a pump out during wash. This would cause the basket to re-engage during agitate and the Motor Controller Module to display this fault.
